When I left in 1999, this same radio station had been the number one station for 13 consecutive years!
You can hear what sounds like men and women's voices; the SAME VOICES over and over, as if they were in there TOGETHER, at one place (the place where the microphone had been lowered.)
Before listening to it, I strongly suggest that you ask the LORD's guidance and protection because (since!) it is EXTREMELY DISTURBING.
May God bless you and protect you!
